Reportedly, the #WelshLanguage text was actually wrong.

#EmergencyAlerts #MobileTelephones

@Writertrev "first" is probably appropriate. There might be a second one, given that we know from this one that part of the system doesn't yet work.

Well _someone_ has to do a poll.

Note that #2G and #3G 'phones weren't expected to get an alert. That was documented.

Those of you with a technical mind and an Android 'phone can actually read the code for what your 'phone is going to do this afternoon.

There's no need to get it second-hand from journalists who turn a full-screen system-modal dialogue into some kind of unspeakable evil that won't permit you to use your 'phone until the government lets you. UTSL!

@solderandchaos It's twaddle.

@revk has it right.

It's a message for sound on, possibly repeated several times, then a message for sound off, again possibly repeated several times. They aren't stored. A 'phone that is powered off (not in sleep mode, but with _no actual electrical power_ to its radio receiver, i.e. battery removed) cannot possibly receive either message. Powered-on 'phones ignore the repeats because they have the same message IDs.

@aroundthehills @pixiepippi

That's just nonsense. Cell broadcast alerts are turned on by the current cell tower, and then turned off by the tower 10 (or whatever length they choose) seconds later. If the 'phone isn't powered (i.e. battery removed) during that period, it won't ever know that anything has happened. Its radio receiver will have not been powered at the times of either transmission.

As I noted in https://mastodonapp.uk/@JdeBP/110243870032616840, I have mine turned on, after _years_ of it being turned off, just to see what happens, which is _supposed_ to be nothing at all. It will be quite amusing if something actually does.

I must remember to look around again for some kit to cope with when #VirginMedia will break my land line later this year, too. I saw some on eBay a fortnight ago, but missed it.

#EmergencyAlerts #MobileTelephones

I turned off cell broadcast reception on this 'phone _years_ ago. It seemed pointless to have it on. No good use was ever being made of it in this country.

I've turned then back on today to see if anything happens. I'm actually quite intrigued.

And yes, I'm also interested in whether it will fall back to 2G in the future.

(And yes, that's going to happen at about the same time that Virgin Media is going to break my land line this year.)

#EmergencyAlerts #MobileTelephones

I have a small bit of news for the doom-mongers who think that all of the 'phones in the U.K. will go off tomorrow afternoon. Mine won't.

Not because it's a secret 'phone. Not because I've done the magic incantations. Not even because it isn't capable of receiving cell broadcasts. It has the capability.

But because the government decided not to support 3G 'phones in this system.

At least, that's what the government WWW site says.

#EmergencyAlerts #MobileTelephones

It would be funny if it weren't sadly ironic.

The government knows that Google's #Android CellBroadcastReceiver &al. apps display a full screen dialogue, with no title, even when the device is locked, and that overrides the ◄ button.

They know that some people are going to complain that they didn't know to press OK, and couldn't do anything else until they did.

So they explain that.

So those people instead complain that the government is going to disable their 'phones.

@Archie8

As requested: You're a conspiracy theorist. Who doesn't know how mobile 'phones work.

Weeding out inactive identities is a matter of simple billing records cross-reference, and doesn't need a new emergency alert system. It can already be done. Cell broadcasts aren't acked, in any case.

And the alert only prevents use of other features whilst it is alerting but unacknowledged. It's roughly what we used to call a system-modal dialogue.

Only in cartoons do people have mobile 'phones _and_ a rotary dial telephone and a clockwork clock that's actually wound up and ticking. (-:
